A conservative business advocacy group is escalating its feud with Rep. Alexandria Ocasio-Cortez (D-NY), spending $100,000 on billboards in Times Square and propping up her primary opponent ahead of the June 25 primary.

The Job Creators Network is endorsing Ocasio-Cortez’s Democratic challenger, Martin Dolan, a moderate who the group believes supports small businesses. The group is launching three billboards in Times Square, slamming Ocasio-Cortez’s record and calling on primary voters to vote for Dolan.
